Le Roy H. Rand, Brooklyn, N. Y., assignor to Band Rubber Company, Brooklyn, N. Y., a corporation of New York Application February 28, 1945, Serial No. 580,281 (01. 128-288) 6 Claims.

This invention relates to baby pants and more particularly to water repellent baby pants having elastic stitched on the margins of the openings, such as at the lower margin of each pant and at the waist.

Prior to the instant invention, baby pants have been made of rubber and of coated fabric. Prior attempts to make baby pants of synthetics utilizing neither rubber nor fabric have resulted in pants to which elastic can not be stitched at the margins with the use of conventional sewing machinery so that such baby pants made of synthetic sheet material may not be readily elasticized at the margins such as at the bottom of each pant and at the waist. Baby pants in accordance with the invention utilize neither rubber nor fabric and are repellent to liquids including water and urine, and can be stitched with ordinary sewing machinery so that elastic bands maybe stitched to the margins at the bottom of each pant and the waist.

It is an object of the instant invention to provide a baby pant made of syntheticmaterial including neither rubber nor fabric which will have elasticized openings for cooperation with the legs and waist of the baby so as to afford the proper protection.

It is a further object of the instant invention to provide a comfortable baby pant which will give the wearer the maximum protection and which may be readily manufactured with conventional machinery.

Other objects and the nature and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings wherein:

Figure 1 is a view in elevation of a pair of baby pants in accordance with the invention;

, Fig. 2 is a fragmentary view in elevation of a portion of the baby pants showing a stitched elasticized margin which has been stretched;

Fig. 3 is a view similar to Figure 2 with a part shown in section.

Referring to the drawing, the baby pants l0 are made of sheet material manufactured as described below and comprises a stitched, elasticized and gathered waist portion l l, a stitched, elasticized mediately adjacent the marginal end of the sheet,

material I! which forms the body of the baby pants and the elastic band It and margin of the sheet material I] are bound by the folded binding material It and the stitching it.

The sheet material for the baby pants in accordance with the invention is manufactured or compounded on calendering equipment. resin may be of the vinyl family such as the copolymers of vinyl chloride and vinyl acetate. The plasticlzer may be di-octyl-phthalate or the reaction product of phthalic anhydride and butylcellosolve or a similar plasticizer. A heat stabilizer, such as calcium stearate, is included, which heat stabilizer in addition to other properties, facilitates the proper processing of the material without affecting its color. A lubricant, such as stearic acid is added and also assists in the processing. The pigment which has among other functions, the function of filling, coloring and imparting good agingcharacteristics is added in the calendering process. Titanium oxide and a small quantity of organic blue may be used as the pigment. It is also necessary to use a solvent which may be selected from one or more of the following group: acetone derivatives, methylethyl ketone,

or esters. Similar solvents may also be used.

A sheeting for the baby pants of approximately the following proportions has been found to give excellent results:

After the materials'have been compounded, sheeted and calendered, the resulting film has a shiny or patent leather effect on its surface'which prevents soil from adhering to it. Former sheetings or film products used for baby pants had quite a difierent surface so that if a child wearing such prior baby pants sat on the floor, the baby pants picked up dirt which was not easy to wash oil. The film in accordance with the invention can be readily cleaned by simply sponging it off. The film in accordance with the invention is capable of being boiled, washed and ironed. It also remains flexible and does not tear very readily.

The resulting film-like sheet-is then cut into a shape corresponding to the front and back of the baby pants which front and back are integral with each other and connected to each other by the material at the crotch. Side seams are formed so as to connect the front with the back to com- Theplete the baby pants construction with the exception of stitching the margin of the waist "and the margin of the openings for the'legs with elastic material. An elasticized binding is then stitched over the margins of the two leg openings and the waist to complete the baby pants.

The stitching is ,efiected with conventional sewing machinery and the film, which is quite thin, being only a few thousandths of an inch in thickness, satisfactorily holds the stitches which do not pull out even though the garment be used quite roughly. The stitched garment may be washed, boiled and ironed without affecting the strength of the stitches materially so that after repeated washings, boilings and ironings, the garment is still serviceable.

In order to make the baby pants more comfortable to the wearer without affecting the other advantages inherent in th material referred to above, silica gel or silica aerogel in the amount t approximately of the total weight of the compound may be added as by the addition of silica gel or silica aerogel the resulting film permits the passage of moisture vapor without detracting from the water proofing quality thereof.

In a sense, it permits the film to breathe." The addition of silica gel or silica aerogel to the film 1 compound in the proportion specified does not afiect the strength of the stiched joint at the margins of the leg openings and waist of the baby thread, said film being compounded of vinyl resin, plasticizer, calcium stearate, stearic acid, pigment, a silica gel, said film and said stitching 'tic band stitched to said body opening with cooperating to provid a relatively strong joint capable of withstanding repeated washings and ironings.

2. Baby pants comprising a body portion of synthetic film material, a body opening, an elastic band stitched to aid body opening with thread, said film being compounded of vinyl resin, plasticizer, calcium stearate. stearic acid, pigment, silica aerogel, said film and said stitching cooperating to provide a relatively strong Joint capable of withstanding repeated washing and ironings.

3. Baby pants including a body portion made of synthetic film generally in accordance with the following formula:

. Parts by weight Vinyl resin 100 Plastlcizer Calcium stearate 1 /2 Stearic acid 1 Pigment Approximately 25 and approximately 10% by weight of the above of a silica gel.

4. Baby pants including a body portion made of synthetic film generally in accordance with the following formula:

Parts by weight VYNS vinyl resin Dioctyl phthalatp 70 Calcium stearate 1 Stearic acid 1 Titanium oxide 25 Organic blue and approximately 10% by weight of the above of silica aerogel.

5. In a baby pants, a joint made by stitching an elastic band to a synthetic film, said synthetic film being compounded of vinyl resin, plasticizer, calcium stearate, stearic acid, pigment and a silica gel, said Joint comprising thread passing through overlying piercing in the elastic band and the film.

6. Baby pants including a, 'bodyportion made 45 of a compounded synthetic film material includins vinyl resin, plasticizer, and a silica gel.
